BACK-BAN o BUCKLE.

SPECIFICATION forming part of Letters PatentiNo. 694,727, dated March 4,1902.

Application filed ctoher23, 1900. Serial No. 84,053. (No model.) I

To all whom it may concern.-

Be it known that I, DEMPSEY T. BRYAN, a citizen of the United States,residing at Rockymount, in the county of Edgecombe and State of NorthCarolina, have invented new and useful Improvements in Back-BandBuckles, of which the following is a specification.

My invention relates to improvements in back-band buckles, all of whichwill be full y described hereinafter, and particularly toferred to inthe claims.

The principal object of my invention is to provide a simple and cheapback-band buckle having at the ends of the base-slot laterallyextendingessentially U-shaped ears or projections and a clamping member having aslot interlocking with the laterally-projecting U- shaped members, theouter wall of the slot of the clamping member coactin g with the inneredges of the walls of the base-slot to lock or clamp the back-band andto allow it to be readily adjusted.

A further object of my present invention. pertains to details ofconstruction, which will be particularly pointed out hereinafter.

In the accompanying drawings, Figure 1 is a perspective View of mypreferred form of buckle, the back-band omitted. Fig. 2 is a transversesectional view showing the backband in position therein. I Fig. 3 is aperspective View showing the buckle formed from wire or a strip of metalinstead of sheet metal,

as illustrated in Figs. 1 and 2.

Referring now to the drawings, A represents a base-plate which, as shownin Figs'l and 2, is composed of sheet metal.

band-receiving slot at, the ends of which are provided withlaterally-projecting essentially U-shaped ears or projections 12. Itwill be noted that the said laterally-projecting U- shaped ears have theinner ends of their U to communicate with the ends of said slot and toin effect constitute a base-plate with an essentially U-shaped slot, or,in other words, aslot with laterally-extending ends. Projecting from onewall of the base-plate slot is an arm a, which has its extremity (whenthe buckle is completed) bent into the form of a hook-shaped arm cl. 7

I The clamping member B in Figs. 1 and 2 is formed of sheet metal and isprovided with This base-plate is provided with an elongated backanelongatedslot e, which is of alength sotficient to embrace thelaterally-extending ears Z7, as'shown in Fig. 1. the outer edge of onewall of said slot e is an outwardly-curved arm f, which is adapted torest under the free end of. the hook d, as illustrated. When the partsare in operative position, the clamping member B rests upon the upperface of the base-plate, and the rear Web of the clamping member formedby the slot e passes through the slot in the baseplate' and rests'withinthe laterally-extending U-shaped ears. The back-band passes the're'arweb of the clamping member and out through said slot in the base-plate.When ber) together and to hold the trace in position within thehookagainst accidental removal. In order to place the twosaid members tofromsheet metal, as shown in Figs. 1 and 2, or of wire or a strip of. metal,as shown in Fig. 3, or from other forms of metal or suitable material,the outer web of the clamping membase-plate slot (with the clampingmember in the position shown in dotted lines, Fig. 1) and the clam pingmember then turned over to operative position before the hook'd has beencompleted. The book is then completed by turning its extremity downoutside of and overlapping the extremity of the arm fiwhich locks thetwo parts together against removal, as will be readily understood. Thisconstruccheap to produce and is devoid of any pivotal connectionsbetween the parts, while at the same time theyare locked in operativeposition. laterally, as shown, form round corners,which will not injurethe animal when the buckle turns to one side, as it sometimes does.

In Fig. 3 I show a buckle constructed in all essential features likethat shown in Figs. 1 and 2, only that it is constructed from wire or astrip of metal, which may be square in cross-section, as shown in Fig.3, or of any Projecting from through the slot in the base-plate andaroundstrain is brought upon the back-band, the

gether after theyhave been formed either' ber formed by the slot eispassed through thetion of a back-band buckle isvery simple and The endsof the base-plate being bent outward from the base-plate, and a clampingmember having a transverse slot of a length and width sufficient toextend from ear to ear, and to receive the inner portions of said U-shaped ears, the outer Wall of the clampingmember slot located in a linewith the slot of the base-plate, substantially as described.

2. A back-band buckle comprising a baseplate having an elongatedtransverseslot, essentially U-shaped ears connecting the ends of theWalls of said slot, said ears extending outward from the base-plate,said plate having a hook-shaped arm c, and a clamping member having atransverse slot of a length and width sufficient to extend from ear toear and receive the inner portions of said ears, and an armfcxtendingunder the hook of the said arm 0, substantially as described.
